Here are several ways to donate:

The One Fund Boston: Gov. Deval Patrick and Boston Mayor Tom Menino established this fund after the attack and it . Visit onefundboston.org to contribute.

As of Wednesday night, organizers said corporate and individual donors had contributed $7 million to the fund. Kenneth Feinberg, a Brockton native who ran the Sept. 11th Victims Compensation Fund and other high-profile accounts to assist people affected by disasters, has been named to administer the fund, pro bono.

Charity Navigator, which evaluates charitable organizations, usually recommends against supporting brand new funds set up in a time of crisis. However, the organization said on its website that the caliber of the One Fund’s leadership and media scrutiny “hopefully will help ensure that the fund does as it promises it will do.”

Coakley’s office said the One Fund is among charities “reputable and worthy of financial support from the public,” and organizations such as the American Red Cross have pointed donors to the One Fund if they want to directly support victims.

Organizers of the new fund already have filed paperwork to register as a nonprofit.

Red Cross: The American Red Cross, which has aided victims since Monday’s attack, is accepting donations to its Red Cross Disaster Relief Fund at redcross.org. Donors also can text REDCROSS to 90999 to make a $10 donation. Contributions assist Red Cross relief efforts everywhere.

As of Thursday, the organization had provided about 500 blood products to Boston-area hospitals, served some 7,000 meals and snacks and provided other services.

While Red Cross had enough blood to respond to the Marathon attack, it has a constant need for more, a spokeswoman said Thursday. In days and weeks ahead, Red Cross encourages donors to schedule an appointment to give blood by calling 1-800-RED CROSS or visiting redcrossblood.org.

Boston First Responder’s Fund: At least six Boston police and firefighters unions set up this fund after the bombing to aid victims.

Injured Marine Semper Fi Fund: This nonprofit has established a Boston Marathon Relief Fund as part of its existing America’s Fund to assist victims of the bombing.

According to its website, the Semper Fi Fund has raised $74 million over the past decade to help injured or critically ill U.S. troops and their families. Assistance from the Boston Marathon Relief Fund “will start with the most critically injured and expand as we receive donations,” the website says.

To contribute, visit americasfund.org/donate. Click “yes” for the question, “Is this donation in support of an event, campaign or fundraiser?” Select “Boston Marathon Relief Fund” from the next drop-down menu.

Charity Navigator has given the Semper Fi Fund its highest four-star rating, and the group is registered both as a nonprofit and with the attorney general’s Non-Profit Organizations/Public Charities Division.

The Patriots and Robert Kraft: Patriots owner Robert Kraft has pledged to match up to $100,000 in donations to assist Marathon bombing victims through the charitable foundations of the New England Patriots and New England Revolution.

Contribute online at patriots.com/donate. In the field provided, donors should write “Boston Marathon.”

The website says Kraft will donate all contributions and his match to the One Fund.

Kraft’s foundations are registered with both the IRS and Coakley’s office.

Patriots players have pledged support, too.

Technology Underwriting Greater Good: This organization, which represents the region’s tech companies, entrepreneurs and venture capitalists, said on its website it had raised nearly $180,000 as of Thursday for victims of the Marathon bombing.

On Wednesday, TUGG said it would donate the first $100,000 it collected to the One Fund. All contributions will go to victims, the website says.

Charity Navigator said TUGG is registered as a charity, but has not yet been rated because it is too small. Visit tugg.org to donate.
